ETM’s Ku-band satellite uplink amplifiers packaged in ruggedized three rack-unit enclosures have been designed specifically for the demands of fly-away, truck and other mobile applications. Easy to read displays allow the microprocessor control to clearly communicate detailed status and monitoring information. These ETM amplifiers combine the latest
technology, ETM’s 27 years of TWT experience, and design features based on in-the-field operation.
■ Universal Power Input is achieved through the use of a wide input (99 to 255 vac, 50/60 Hz) power factor correction circuit. This circuit also reduces the power consumption and has enabled ETM to certify the unit to the European standards for earth stations described in ETS 300-327
■ Ease of Operation is provided by a 20-character by 4-line fluorescent display and straight-forward four button control. Complete monitoring is provided including forward and reverse power, TWT voltages and currents, and operating temperatures. Modular design reduces cost of long-term maintenance.
■ In-The-Field Reliability is ensured by ETM’s rigorous testing program. Every ETM amplifier is subject to an environmental burn-in that includes temperature cycling, multiple cold starts from -20°C, and, as required, shock and vibration testing.
